Medik8 Crystal Retinal 20 is a night serum that helps experienced Crystal Retinal 10™ users to intensify results. This cult best seller at its highest ever strength features 0.2% retinaldehyde, a powerful derivative of vitamin A with next-generation anti-ageing results.

Unmatched in its age-defying power, retinal can deliver results comparable to clinical-grade vitamin A up to 11 times faster than classic forms of retinol. This ground-breaking overnight serum visibly minimises fine lines and wrinkles; firming and plumping the complexion to resurface skin texture and soften the face. Featuring hyaluronic acid, glycerin and vitamin E, it hydrates skin at every level to deliver a supple, even-toned, more youthful-looking complexion. 

Note: You should be comfortably using Crystal Retinal 10™ every night for 3 months or completed 2 full tubes before moving up.
